{UNITED STATES PATENT o-FFmE PIERRE P. GILLES, DECEASED, LATE OFSPRINGFIELD, MASSACHUSETTS, BY FLORENCE MAY GILLES, ADMINISTRATRIX, 0F. CORTLAND,-NEW YORK OIL BURNER Application filed July 31,

This invention relates to improvements in oil burners of the type in which the oil and air are mixed together by means of a rotatable turbine member through which the oil and air are forced.

Broadly, the invention comprises a base member which is formed with a groove'or channel around the outer upper edge for the purpose of collectingand returning any surplus oil. A vertically arranged shaft is em- 1 terial for producing a noiseless drive. The

invention includes means for distributing the air through a member having inclined shaped partitions which are located adjacent the oil outlets.

Referring to the drawings Fig. 1 is a plan view of the burner removed from the furnace compartment showing the vertically arranged shaft, the cone shaped bowl, the pilot jet and the driving connections between the shaft and operating member.

Fig. 2 is an enlarged elevational view partly in section, showing the pilot jet and the rotatable cone-shaped member in side elevation and located within the furnace.

Fig. 3 is an enlarged vertical sectional view on the line 3-3 of Fig. 1 showing'the detail construction of the rotatableturbine inember, the driving means for the member and the oiling system. Q

Fig. 4 is a horizontal sectional view on the line 44 of Fig. 3 of the turbine member on a larger scale, showing the construction of the inclined partitions of the rotatable turbine member.

Fig. 5 is a detail, sectional view onthe line 1928. Serial No. 296,617.

55 of Fig. 4and Fig. 6 is a modification of the burner mixer. 1

Referring to the drawings in detail:

1 designates the base piece of the burner which is supported by means of'the legs 2. 1 is a cylindrical upright or castingthat is secured to the base 1 by'means of the screws 1. This] base piece is formed around its 'outer'edge with the voil collecting g1'oove'4 which terminates at the oil strainer -5. 6 designates the pipe which conducts the oil back to the oil supply tank 7 from the basin '69. Mounted on the base piece is the electric motor 8. Connected to the motor Sis a shaft 9, the inner end of which is supported in the bearing 10. 11 representsthe ball bearing construction for supporting the shaft 9. 12 is a slidable plate located in the bearing 10.

This plate is formed with the openings 13. 14 v is a plate which is threaded into the end of the bearing 10, and 15 is a spring for normally forcing the plate 12 against the bearing 16. The opening 13 registers with'the opening 17 of the ball bearing. "On the' inner end of the shaft 9 is secured the cone pulley 18 by means ofthe woodruff key 19. This pulley is formed with a leather face 20. This face piece is secured tothe cone pulley 18 with the screws 21. 22 is a vertically arranged shaft that is supported at the bottom by the ball bearings 23 and at the top with the ball bearing 24. 251s a sleeve which encloses the shaft 22. 26 is a cone shaped pulley secured to the shaft 22 by means of the key 27 28 is a pipe which extends from the recess 29 to the upper recess 30. The lower end of the shaft 22 is attached to the plate 31. 32 is another plate that is attached to the shaft 22. The plates 31 and 32 serve as a pump to force theoil upward through the pipe 28 into the space 30, then downward through ball races 33, then through the pipe 34 into the space 35 where which is located a'bove the upper edge of the part 50 which provides an annular oil escape space 51.- 52 is an internally threaded cap that secures the saucer shaped member '48- on to the upper end of the shaft 22. Formed in the cap piece is a passageway 53' which receives the discharge'end of the oil supply pipe 54. The oil from the passageway 53 flows upward through the nozzle piece 55 which is formed with a very small opening.

Surrounding the cone-shaped member 42 is i a cap 56 which issec-ured to. the cap piece 40 by m'eansof the bolts 57 only one of which is shown and a spring 58'to provide yielding .or an elastic side bearing or support for the cone-shaped member 42; I

Referring toFig. l, 59 is a pipe that is connected with the gas main of the city for supplying the pilot jet 60. 61 is a cap located over the pilot jet'60 which is formed with an opening 62. The turbine member 44 is lo,- cated withinthe furnace of the heater which may be either hot water or steam. The re fractory material of the furnace is indicated at 63. It will be noticed that the oil groove 4 islocated immediately below the passageway 64, to receive and carry off any surplus oil or to carry off the oil should the burner go out. The pipe 54, it will be understood, extends to the pump 65, and connected with this pump is a pipe 66 that leads back to the fuel tank 7 66 is avalve for controlling the oil from the basin 69. 67 is abelt extending 69 toopen a circuit to the motor. A pipe '70 conducts oil from thebasin 4, in'case the burner goes out, to the drip basin and a pipe 71 connects the pipe 54 leading to the burner to the drip basin which basin is connected to the tank 7 by a pipe 7. This is so in case pipe 54 is closed, oil will be delivered back to tank 7. r

The weight of the collected oil in the drip basin 69 will automatically cut off the electric current to the motor 8, thereby preveuting furthersuction of the oil from the tank. The operation of the dripbasin 69 will open an electric. switch 69 in the motor circuit.

The operation is as follows: Itis assumed that oil is flowing throughthe pipe 54 into passageway .53, then through then ezzle piece her 44. The flame is therefore spread out ward in a mushroom manner within the furnace. 72 is a valve which automatically controls the flow of gas to the pilot light 60. This valve is operated by the pressure of the pump and does not form any part of the invention. V i l From this ldescriptionit will be-seenthat there has been provided an oil burner which,

by, means of a rotatable turbine member thoroughly mixes or atomizes the oil and air in the furnace compartment. 44v extends above the spreader 48 for thoroughly mixing the oil and air as the same is rapidly rotated.

Referring to Fig. 6, 73 designates a flame spreader plate which is located, as shown, P

a short-distance above the upper'peripheral edge 74 of the turbine fuel mixing member 44. This plate issecured to the upper end of Itheshaft 22 bymeans of the short stud .75 which, as shown, is internally threaded at 76 for connection with the threaded upper end of the shaft 2.2. Its upper end is formed with a threaded end 77 to receive the secure in'g nut 78. The annular space 79 permits the V flame tobespreadout in a horizontal direction as the mixing member 44v is rapidly rotated.
